I haven't dealt with the company but do know the aircraft owner and Marco Kalweit who flies the aircraft.
It is a very nice almost new S2C and Marco used it to good effect in 2009 coming first in the Intermediate nationals and 3rd in the Advanced nationals.
Their website doesn't say who will be doing the training but if it is him then I don't think you will have any complaints.
Marco was also the pilot who got his PPL in a Pitts (this one). There was an article in Pilot about him. However he had done more than a little gliding beforehand.
